User Equipment and Method for Managing Out-Of-Order Packets

2. The UE of claim 1, wherein the network information comprises an operator information, a network type, a signal strength, a latency, an out-of-order rate and packet loss rate.

3. The UE of claim 1, wherein the application information comprises types of applications, 5-tuple information of applications, and process Identity (ID) of applications.

5. The UE of claim 4, wherein the reorder timer setting module updates the filter rules according to new network information and new application information collected by the collector.

7. The UE of claim 6, wherein if the packets are in order, the checker directly pushes the packets to its corresponding application through the TCP/IP stack.

8. The UE of claim 7, wherein if a first out-of-order packet of the out-of-order packets matches with one filter rule in the multi-reorder queue table, the checker allocates the first out-of-order packet to its corresponding reorder queue of the multi-reorder queue circuit, and if a second out-of-order packet of the out-of-order packets does not match with any filter rule in the multi-reorder queue table, the checker allocates the second out-of-order packet to a normal queue of the multi-reorder queue circuit.

9. The UE of claim 1, wherein before a reorder timer corresponding to one reorder queue of the multi-reorder queue circuit is not expired, if a bitmap is complete, the multi-reorder queue circuit pushes the packets in the reorder queue to its corresponding application through the TCP/IP stack.

10. The UE of claim 1, wherein when a reorder timer corresponding to one reorder queue of the multi-reorder queue circuit is expired and a bitmap is not complete, the multi-reorder queue circuit pushes the packets in the reorder queue to the TCP/IP stack.

11. The UE of claim 1, wherein the multi-reorder queue circuit checks sequence numbers of the out-of-order packets, wherein the sequence numbers are supported by a higher layer protocol.

12. The UE of claim 11, wherein if the sequence numbers of the out-of-order packets are continuous, the multi-reorder queue circuit pushes the out-of-order packets to its corresponding application through the TCP/IP stack.
